Abstract: Systems and methods for providing optical quantum communication networks based on rare-earth ion quantum bits (qubits) entrapped in solids are presented. According to one aspect a qubit is provided by an 171Yb3+ ion doped into a YVO crystal structure. A nanophotonic cavity fabricated in the doped crystal structure provides a zero-field energy level structure of the ion with optical transitions between ground and excited states at a wavelength longer than 980 nm. A subspace of the qubit is provided by two lower energy levels at the ground states separated by a microwave frequency of about 675 MHz. Addressing of the optical transitions is via first and second lasers and addressing of microwave transitions at the ground and excited states are via respective microwave sources. A single-shot readout sequence of the qubit based on two consecutive readout sequences on the optical transitions separated by a microwave pumping of the ground states is presented. Assignment of a readout state is conditionally based on combined states detected in the two consecutive readout sequences.

Abstract: An optical device has a first metasurface. A high-contrast pattern of the first metasurface is operable for modifying, over a first phase profile, a phase front of an incident light beam. A second metasurface, is disposed over a plane parallel to the first metasurface with a second high-contrast pattern and operable for shaping, over a second phase profile, the modified phase front of the incident light beam into a converging spherical phase front. A spacer layer, in which the modified phase front of the incident light beam diffracts, is disposed in a controllably changeable separation between the first and second metasurfaces. Controllably changing the separation between the first and the second metasurfaces by a first distance correspondingly changes the position of the focus point of the converging spherical phase front by a second distance.
